BOMA Standards

As commercial office buildings continue to evolve with complex architectural designs and growing tenant demands for amenity-rich building features, accurate measurements are more critical than ever. Commercial buildings must adhere to the measurement standards set by The Building Owners and Managers Association (BOMA). BOMA is an international association of commercial building owners, brokers, providers, and professionals that serve the industry.

BOMA’s standard is recognized as the most comprehensive standard for calculating square footage for commercial buildings and was most recently updated in 2010. The standard is used for all commercial buildings, including office, retail, warehouse, industrial, and multifamily rental buildings.

Staying Up-to-Date

We at ACS strongly encourage building owners to be up-to-date with the current BOMA requirements for the following reasons:

  • BOMA 2017 for Office Buildings (ANSI/ BOMA Z65.1-2017) is currently the predominant industry standard for measuring office building lease areas in the United States.
  • When a revised or updated standard is published or certified by BOMA, requirements may change depending on factors such as rentable areas of individual lease spaces, common area, and load factors, etc. Potential changes may affect measuring methods, the definition of common areas, treatment of flood penetrations, etc.
  • Even without the adoption of a new BOMA standard, individual Rentable Area values can change over time when certain areas of the building are reclassified.
  • A 2% margin of error is typically accepted in the industry. Differences between two parties’ measurements can exist due to varying physical measurements taken or individual interpretations of how the BOMA standard may apply in unique situations of building measuring and areas of classification.
